Answer:
The plasmid must express a gene for ampicillin resistance (the protein product of the <em>bla</em> gene codes for beta-lactamase, the protein that breaks down ampicillin). The colonies on the ampicillin plate are antibiotic resistant. This means that they have taken up the transformed plasmids expressing both the <em>bla</em> gene and the GFP gene.
Explanation:
The transformation involved the genetic modification of a plasmid to incorporate the gene encoding the green fluorescent protein (GFP) from jelly fish. GFP makes cells glow under UV light.
In genetic engineering, scientists use antibiotic resistance as markers to indicate cells that have been transformed. By incorporating an antibiotic resistance gene such as <em>bla</em> into the vector (plasmid) and then growing the cells in antibiotic media, scientists determine which colonies have taken up the plasmid. Therefore, if the cells survive, this means that they contain the plasmid with antibiotic resistance gene as well as the GFP gene.
Answer:
One of the positive consequences of nuclear power plants is that it produces small amounts of air pollution. Comparing it to coal power plants, nuclear reactors has less or no production of air pollution while in operation. It is by far one of the power plants with least contribution to air pollution.

If a car's acceleration is negative, I'd say the car is slowing down.
Selective logging—the practice of removing one or two trees and leaving the rest intact—is often considered a sustainable alternative to clear-cutting, in which a large swath of forest is cut down, leaving little behind except wood debris and a denuded landscape.
